Bigg Boss Tamil 2 written update, September 7, 2018: Riythvika becomes captain for the first time

In the latest episode of Bigg Boss Tamil season 2, Aishwarya Dutta and Mumtaz had an early morning discussion in which Mumtaz was seen giving suggestions about her ligament issues.
Aishwarya was seen speaking in English. Hence, the alarm rang following which, 5 inmates had to jump into the swimming pool following the alarm.
After making the mistake, Aishwarya didn’t request the inmates to jump into the water.Therefore, Vijayalakshmi, Janani, Riythvika and Bhalajie discussed that it is not necessary to do the task as Aishwarya didn't request them.
Due to the arrogant attitude of Aishwarya, no one was ready to jump into the water. When Yashika asked about this, Riythvika, Janani and Vijayalakshmi said that they are ready to jump into the water but Aishwarya should request them.
Aishwarya, on the other hand, was seen quite reluctant to do the same.
Yashika also tried to convince Aishwarya but fails.
Finally, when Riythvika and Janani were jumping into the pool, Aishwarya arrogantly said that she will continue to speak in English. As Aishwarya was continuously speaking in English, the alarm went on again.
Being a captain, Yashika tried to convey the rules to Aishwarya but she misunderstood her. Aishwarya blamed that Yashika is biased and the fight continued.
Mumtaz used the steamer to dry her clothes. She saw Vijayalakshmi coming in and wrongly assumed that Vijayalakshmi might use the steamer. She left the place without switching the steamer off. Vijayalakshmi complained about this to Bigg Boss.
Vijayalakshmi sought clarifications from the inmates about the steamer issue. Mumtaz accepted her mistake that she didn’t switch the steamer off. The two continued to argue regarding the issue.
Riythvika read out the next announcement of Bigg Boss that, Yashika’s captaincy has come to an end. Everyone was given a chance to participate in the task of selecting the new captain. The inmates had to perform a task using the 7 wooden blocks.
Riythvika completed the task successfully. Hence, she became the captain of the house, for the first time. Following this, Riythvika segregated the inmates into different teams for performing household chores.
Mumtaz wanted to confirm what Aishwarya spoke about her when she was not ready to colour her hair for Riythvika. Aishwarya accepted that she had commented negatively about Mumtaz.
